Cranage LISN Model MS461-100A One Line
V-Network (MIL-STD-461E) |
|
General
A line impedance stabilising network (LISN) is used to provide a defined
impedance source on each input supply line to the EUT so that measurements
of differential and common mode radio noise current can be made. The
specified line impedance is conditional on the measurement socket being
terminated with a 50W non-inductive resistor
and the noise current is measured using a current probe.
Technical Specification
Model MS461-100A LISN is a three terminal device, one terminal
earthed, to be series connected between the power source and the primary
power input of the EUT. It is a robust, high stability unit which meets
the impedance/frequency characteristics specified in MIL-STD-461E (20th
August 1999). A shielded input capacitor (8mF)
and series resistor (5W) is incorporated
for performance and safety reasons. The measurement socket is externally
terminated with a high-surge 50W coaxial
resistor (also available from Cranage). The case of the LISN is bonded
to the ground plane via four M6 screws. An M8 earth stud is also provided
for additional earth bonding.
